What you and other WTS apologists fail to recognize is the limited scope of "expertise" that elders and/or religious leaders have or should be permitted to have. Elders are allowed "freedom" to exercise authority as it relates to spiritual issues for their adherents. Religious freedom allows for adherents to seek spiritual assistance from "qualified" ministers who they look to as spiritual leaders. However, when the issue crosses spiritual limitations and enters the arena of being illegal, elders should remove themselves from such matters and defer to trained professionals who have the experience, authority, and resources to address such matters in harmony with the law.
The WTS by discouraging members from taking "brothers to court" thus encourages them instead to go the elders first. The WTS by requiring the elders to first contact the "Legal Department" presumes to place its relative authority above the existing superior authorities. When it's a matter of serious illegal activities like child abuse, rape, or murder, the elders and the WTS is obligated by common sense and love for their adherrents to refuse to handle such matters beyond the realm of spiritual encouragement and counsel. They cannot and should not presume to offer or render legal advice or intervention. The moment they do, they have placed their policies at the mercy of litigants and the courts.
In summary, elders, whether of the congregation or the WTS, are limited in the scope of their authority to being spiritual advisers and counselors. Clearly child abuse, rape, and murder are not spiritual weaknesses, they are heinous crimes that render "repentance" to be irrelevant as to whether the legal authorities get involved.
Your reasoning is completely devoid of this fact and literally makes me throw up!
